DUBAI // Caroline Wozniacki ensured she will regain the No 1 ranking from Kim Clijsters after beating Shahar Peer of Israel to reach the semi-finals of the Dubai Tennis Championships.
The 20-year-old Dane only lost her top ranking on Monday, but she will claim it back when the new rankings are released next week after seeing off Peer 6-2, 6-4.
Wozniacki wrote on her Twitter page: "Won my match against Shahar Peer 6-2 6-4, playing the semis tomorrow and got my number 1 ranking back :))"
That prompted a reply from Clijsters: "Congrats :-) ha ha."
Wozniacki first rose to the top in October, replacing the injured Serena Williams, but she is still yet to reach a grand slam final. She lost to Li Na of China in the Australian Open semi-finals in January.
However, she was among the most consistent players in 2010. She won the most tournaments and appears in good form in Dubai, easily beating an ailing Anna Chakvetadze and then only dropping a game in her third round match against Japanese qualifier Ayumi Morita.
Last year, Peer reached the semi-finals - beating Wozniacki on the way. The No 11-ranked Peer lost to Serena Williams in the semi-finals.
This time around, Wozniacki went up early 3-0 in the first set and was never seriously challenged mostly due to the erratic play of the Israeli who had 34 unforced errors - more than twice that of the Dane. Wozniacki went up again 4-0 in the second set, before Peer seemed to get her game going.
Peer reeled off two games to make it 4-2 and then closed the gap to 5-4 before Wozniacki completed the win with an overhead smash.
